Abstract (en)
[origin: US2017292510A1] A hose pump includes a hose bed having a counter support, a carrier disk rotatable relative to the counter support, and a number of pinch rollers and guide rollers arranged on the carrier disk. A guide roller is arranged between two consecutive pinch rollers, and the pinch rollers press a hose inserted into hose bed against the counter support, while pinching the hose when the carrier disk is rotating in the conveying direction to transport the fluid in the hose. To ensure reliable threading of a hose section of a pump hose, when the hose section is somewhat too short and to prevent unthreading of the inserted hose section during operation of the hose pump, the angular distance between a guide roller and the pinch roller preceding the guide roller in the conveying direction is greater than the angular distance between this guide roller and the pinch roller following the guide roller in the conveying direction.
